老年人是肺炎高发人群。据统计,60岁以上老年人肺炎发病率为25%,死亡率高达20%,占老年人死亡原因的第4位。虽然年龄本身可能不是引起老年肺炎发病和死亡率增加的最重要危险因素,但会使老年人处于危险状态。因为随着机体的老化,呼吸系统解剖和功能发生改变,可导致老年人全身和呼吸道局部的免疫功能降低,肺的净化系统衰退,病原体容易在肺内立足、生长、繁殖,从而导致感染发生,且
The elderly are high risk of pneumonia. According to statistics, the incidence of pneumonia in elderly people over the age of 60 is 25% and the death rate is as high as 20%, accounting for the fourth leading cause of death among the elderly. Although age itself may not be the most important risk factor for the increased incidence and mortality of senile pneumonia, it puts the elderly in jeopardy. Because with the aging of the body, the respiratory system anatomy and function changes can lead to lower systemic immune system and respiratory tract local elderly people, lung purification system decline, pathogens easily in the lungs to gain a foothold, growth, reproduction, resulting in infection, And
